Re: 1.3" SH1106 uOLED Display Module (HCMODU0058 & HCMODU0059)

While testing one of the HCMODU0058 1.3" UOLED displays I accidentally discovered that it somehow works without connecting the GND and VCC pins to a power source! I've repeated this with a number of similar 1.3" SH1106-based OLED modules and they all work even if GND and VCC are left unconnected. I ...

HCuOLEd.Print() won't display zero

If I try to display a variable (int or long) which has a zero value, the 0 doesn't appear on the display! For example, adapting the HCuOLED Example code for HCuOLED_Text_Example, the display should show: -101 A zero:0 -101 A zero:0 -123.05 but instead I get: -11 A Zero: -11 A zero: -123.05 i..e no z...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

OK so I got it working. I had to install the latest Arduino IDE (1.8.7) over the top of the old version so now everything compiles as it should.

Thanks for you help and maybe this can also help anyone else who may have had a similar problem.

Regards,

Phil.

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Well that didn't work :-( Here's the verbose output after copying Wire to the Arduino IDE 160 libraries folder: Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Uno" Using library HCuOLED in folder: F:\Arduino\libraries\HCuOLED (legacy) Using library SPI in folder: F:\Arduino\libraries\SPI (legacy) F:\...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Thanks for the rapid response Andrew. I checked and found that my Wire library is in an older Arduino IDE installation. I'll try copying it to the Arduino IDE 160 folder but oddly, my own sketches using the Wire library all compile ok, but I'm using #include <Wire.h> within the sketch itself and I d...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Any ideas why I'm getting this compiler error regarding Wire.h? Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Uno" In file included from HCuOLED_Text_Example.ino:42:0: F:\Arduino\libraries\HCuOLED/HCuOLED.h:38:18: fatal error: Wire.h: No such file or directory #include <Wire.h> ^ compilation termina...
